Maybe I'm just hysterically paranoid, but I think the WUSA has had a effect on hairstyle choices made by some incoming foriegn players. Riise, Pichon and Prinz have all started to grow out their hair into ponytail length a la US players. I believe this is part of a conspiracy by other national teams to not only learn our secrets of success but also look like us on the pitch so we pass the ball to them.
